Introduction
update time：2024-01-28The interface technology of virtual instruments and USB has received close attention in the field of instrument research and development. The use of USB interfaces for intelligent peripherals for data acquisition and control has improved its bottleneck phenomenon and also strengthened its connection with general computers. The "affinity". The ordinary MCS-51 microcontroller does not have a USB interface, and LabVIEW, one of the virtual instrument application software development platforms, does not provide a USB interface driver. For this reason, the design principles of virtual instruments based on USB and LabVIEW are introduced. As well as USB development methods, a simple development design is proposed. The process of USB development using FT245 BM is explained, and the circuit diagram and written program of the interface between FT245 BM and AVR microcontroller AT90S1200 are given. The installation of two different drivers is introduced. The method of writing LabVIEW application is given, and the written LabVIEW application is given. After debugging, the test results are given.
